I haven't seen it used in a museum context, but in motion picture special
effects, we now more often use fine tungsten wire for the "invisible"
suspension of objects.

It is available in diameters as small as .0009", which is virtually
invisible and is specified to support about 1/3 lb. Thicker wire, say with a
diameter of .005" it is much, much less noticable than even 2 lb.
monofilament, and has a load of about 8 lbs. It does not degrade in
sunlight, but it can be difficult to handle since it is almost invisible and
small kinks or poorly tied knots may cause fatal fatique. We usually coat
knots with cyanoacrlyate adhesive, which may not be appropriate in a museum
setting.

It is possible to suspend large objects with no visible support, especially
if carefully lit. I would be interested to hear if anyone has used this
material in a exhibit or display.
